Introduction
The High Current Edge
family of connectors
provides high reliability and
economy in packages
compatible with industry
standards. While many new
card edge connectors for
signal applications have
moved toward higher density
configurations (0.050"
and 1 mm centerlines),
Tyco Electronics has
redesigned the 0.100"
standard edge product
family to carry more current,
for low power distribution.
This product family includes
the following:
■ CROWN EDGE Products
■ Standard Edge Connector
— 2nd generation
■ SEC-II Power Products
The connectors serve low
durability cycle applications
which do not have the
available room for a
traditional 2-piece power
distribution connector. In
other applications, a low-
profile connector is needed
to allow for better airflow /
less airflow restriction.
This grouping of power card
edge connectors is focused
on providing high current
density with the favored
multi-point contact design
which reduces contact
interface resistance.
The connectors were
used originally in the ISA
Standard for computer
expansion cards. Today
these connectors are being
used in applications such
as; DC-to-DC converters,
low-wattage power
supplies, industrial grade
card extenders and general
low cost I/O applications
requiring durable/rugged
card edge contacts. The
improvements made still
allows use in the original
applications and they
provide a lower resistance
connection due to the high
conductivity contacts
plated with a minimum
30 micro inches gold.
The options include vertical
or right-angle PCB mounting
as well as straddle-mount
configurations for co-planar
PCB applications.
